Ex-NER Wilson Worsdell designed Q6 class 0-8-0 no. 1250 taken in 1936 at an unnamed location but which I believe to be Barnby Moor on former GNR metals as that somersault signal looks very familiar from other images in my collection.
No. 1250 acquired its BR number 63343 in July 1948 and would be withdrawn from service at Hartlepool mpd in June 1965.
